        "Description": "Natural electromagnetic wave emissions at 9 fixed ELF/VLF frequency bands measured at 2sec intervals with the 9-channel ELF/VLF receiver at Tjornes, Iceland. The data is stored together with the magnetic field from the fluxgate magnetometer, CNA from the broad-beam riometer, and the magnetic field from the induction magnetometer.",
